The doping process of polyacetylene and the nature of the charge transfer are of considerable interest.’ In particular Fincher et al. have shown that lightly doped (<O.l%) polyacetylene (CH)x with a variety of acceptors or donors leads to the appearance of new infra-red (IR) active modes at 900 cm-l (width of Q400 cm-l) and at 1370 cm-l (width of Q50 cm-l). This IR activity is independent of the dopant type and is therefore evidence that charge has been transferred to the polyacetylene chain and its coupling with the *Supported in part by the National Science Foundation, under Grant No. PHy77-27084.

N2 - The frequency dependent conductivity of added charge to a dimerized Peieres condensate with N coupled phonons is studied. The electron-phonon system, with electron-electron interactions and pinning effects, yields in the adiabatic and continuum limits an infrared absorption whose structure is independent of the charge configuration. The kinetic mass of the charge affects only the pinning parameter and the over-all magnitude of the absorption. This mass was estimated from experimental data and compared with theoretical soliton and polaron masses.
